1. Molecular approach to characterize ectomycorrhizae fungi from Mediterranean pine stands in Portugal
Stone pine (Pinus pinea L.), like other conifers, forms ectomycorrhizas (ECM), which have beneficial impact on plant growth in natural environments and forest ecosystems. An in vitro co-culture of stone pine microshoots with pure mycelia of isolated ECM sporocarps was used to overcome the root growth cessation not only in vitro but also to improve root devel

2. Óleo essencial de eucalipto como bioestimulador da micorrização e do estabelecimento de mudas de eucalipto e sibipiruna em solo contaminado com cobre / Essential oil of eucalyptus as biostimulator of mycorrhiza and the eucalyptus and sibipiruna tree establishment in soil contaminated with copper
Ectomycorrhizal fungi (fECM) combined with the plant root system improve the absorption of water and nutrients, providing great plant growth, especially in environments with nutritional deficiency or degraded. Due to the fECM and plants live in mutualistic association, allows the fungal symbionts to be benefit, or at least tolerate, the secondary metabolites

3. Ectomicorriza in vitro entre Hydnangium sp. e Eucalyptus grandis e análises de seqüências de genes de Hydnangium sp. / Ectomycorrhiza in vitro between Hydnangium sp. and Eucalyptus grandis and sequences analysis of Hydnangium sp.
Hydnangium sp. é um fungo basidiomiceto capaz de formar ectomicorriza com espécies de Eucalyptus. Os sistemas de micorrização in vitro vêm sendo largamente utilizados para estudar interações micorrízicas, tornando-se um sistema simples e reproduzível para as análises de expressão de genes envolvidos na interação. Neste trabalho, a técnica de mi

4. Identificação de genes expressos durante a fase pré-simbiótica da associação ectomicorrízica entre Hydnangium sp. e Eucalyptus grandis e transformação de fungos ectomicorrízicos / Identification of genes expressed during the pre-symbiotic interaction in the Hydnangium sp.-Eucalyptus grandis ectomycorrhizal association and transformation of ectomycorrhizal fungi
Gene expression in the ectomycorrhizal fungus Hydnangium sp. during the pre-symbiotic interaction was evaluated using an in vitro mycorrhization technique aiming at constructing a suppressive subtractive cDNA library. The fungus was cultivated in the presence of Eucalyptus grandis roots, with no direct physical contact between both organisms. Genes that code

5. Efeito de fungos micorrízicos arbusculares sobre o parasitismo do nematóide das galhas em plantas de bananeira micropropagadas / Effect of arbuscular mycorrhizal fungi on the root-knot nematode parasitism in micropropagated banana plantlets
Banana is one of the most economically important fruits crops and its micropropagation has been stimulated by improving seedlings quality. However, they are sensitive to many pests and pathogens, including nematodes. The arbuscular mycorrhizal fungi (AMF) are symbionts associated to the roots, favoring the growth and the development of plants, also being abl

6. Tissue-Specific and Development-Dependent Accumulation of Phenylpropanoids in Larch Mycorrhizas.
The tissue-specific and development-dependent accumulation of secondary products in roots and mycorrhizas of larch (Larix decidua Mill.; Pinaceae) was studied using high-performance liquid chromatography and histochemical methods. The compounds identified were soluble catechin, epicatechin, quercetin 3-O-[alpha]-rhamnoside, cyanidin- and peonidin 3-O-[beta]-

7. Mechanisms for the development of genetically variable mycorrhizal mycelia in the ectomycorrhizal fungus Laccaria bicolor.
An in vitro study investigated mechanisms for the development of genetically variable mycorrhizal mycelia for Laccaria bicolor. Seedlings of jack pine (Pinus banksiana) grown nonaseptically in an autoclaved soil substrate were given different L. bicolor inoculum treatments. These included (i) a dikaryotic mycelium genotype (D); (ii) D and basidiospores colle
